I know this is an old post, but maybe it will help the next.
I wanted to run the software mainly from my desktop, unknowingly I installed it on my notebook first just to find out they only allow for one install.
I called tech support and they said that I was SOL, because there is not a way to uninstall. I told them that I just bought the calculator and if they didnt want to give me a new code I would just pack it up and take it back and buy another one.
Then she finally said let me talk to the manager… guess what they gave me a serial number. It was pathetic it came down to that, just because they are too lazy to provide an uninstall method.
Also I think you can buy one for a few dollars, not sure on this, but I thought I remember seeing it somewhere on TI's site.
